McKenna was a partner at the media firm McKenna Pihlaja for six years before starting her own firm, McKenna Media.

As IE director, McKenna will oversee teams of consultants for each race and the tens of millions of dollars of spending. Many of those contests feature Democratic women she helped elect while at EMILY’s List and during her previous stints at the DSCC.

“Even as Republicans struggle with bitter primaries, lackluster fundraising and a health care agenda that is deeply unpopular with American voters, we know each of these races will be a fight to the finish and that is why we are thrilled to have Martha’s strategic insight and talent,” DSCC Chairman Chris Van Hollen said in a statement. “Martha’s leadership will be essential to our work to elect Senate Democrats.”

Democrats are defending 26 seats this cycle — 10 of them in states President Donald Trump won in 2016. The party needs to hold all of those, and flip two more seats to win control of the Senate.

McKenna stressed the importance of supporting the candidates.

“Democratic Senate candidates are laser focused on fighting for working families, from protecting health care to standing up against giveaways to big corporations. We need to have their back this election year,” McKenna said in a statement. “I’m honored to be a part of the fight and ready to make sure Senate Democrats have the support they need.”
